Smoke Alarm FAQs
Why should my home have smoke alarms?
You are more likely to survive a home fire if you have a working smoke alarm. During a fire, you may have less than three minutes to escape. Smoke spreads fast, and smoke alarms alert you to the danger and give you time to get out.
What is the difference between a smoke alarm and a smoke detector?
A smoke alarm is a self-contained, single or multiple-station smoke-sensing device. A smoke alarm detects and alarms. A smoke detector is a smoke-sensing device that is not self-contained and operates as part of a central control system. A smoke detector detects smoke and sends the information to an alarm panel.
What types of smoke alarms are available?
Ionization, photoelectric, dual-sensing (ionization/photoelectric), and combination smoke/carbon monoxide alarms.
